ABSTRACT:
A packaging material which comprises a simultaneously coextruded film comprising a conductive ethylene-ethyl acrylate copolymer resin layer containing more than 50 wt.% of ethylene-ethyl acrylate copolymer resin of which content of ethyl acrylate is more than 6 wt.%, 7 to 20 wt.% of carbon black and 0.01 to 1 wt.% of a lubricant, and a polyolefin resin layer.
The packaging material of the invention is superior in antistatic property, moistureproofness, light-shielding, tear strength, impact puncture strength, slipping character and heat sealing properties. Its production is easy because of superior moldability, and generations of blocking, fish eye and pin hole are rare. The packaging material of the invention can be made thinner than the conventional packaging material, and expensive metal foil is not necessary. Accordingly, this packaging material is inexpensive.
